Kings of Leon further "Mechanical Bull" North American trek

Kings of Leon have planned out the second leg of this impending "Mechanical Bull" North American tour, which now reaches into the spring.

The Grammy Award winners already had plans for a 16-city arena trek beginning Feb. 5 in Atlanta. Since last check, a second round of concerts has been added, kicking off March 19 in Phoenix and visiting a dozen major markets, including several Canadian stops.

Blues-rock musician Gary Clark, Jr. will provide opening support for the run. Tickets for most of the second leg go on sale Friday, with more dates being announced in the coming weeks.

Kings of Leon is also slated to be the musical guest on the Dec. 14 episode of "Saturday Night Live," as well as guests on "Ellen" Monday (12/16).

The 2014 outing supports Kings of Leon's sixth studio album, "Mechanical Bull," which surfaced in late September. The 11-track RCA Records release peaked at No. 2 on The Billboard 200 and at the top of album charts in Ireland, New Zealand and Australia. It also debuted at the top of the U.K. Albums chart, making it the band's fourth consecutive record to do so.
